This is a decision on appeal under 35 U.S.C. § 134 from
the final rejection of claims 1-6 and 8-16. Claim 7 has
been canceled.
We affirm.
BACKGROUND
The disclosed invention is directed to the structure of
a magnetic head for detecting a magnetic field.
Claim 1, the sole independent claim, is reproduced
below.
1. A magnetic head for detecting a magnetic field
representing information recorded on a magnetic
recording medium, said magnetic head having a head face
and comprising a multilayer structure with at least one
magnetoresistive layer of magnetic anisotropic
material, said magnetoresistive layer having a central
portion forming a magnetoresistive element located
between two end portions, said magnetoresistive layer
having a longitudinal axis directed from one end
portion to the other end portion, said magnetoresistive
element having an easy axis of magnetization extending
at least substantially parallel to the longitudinal
axis, an electrically conducting layer provided on one
side of said magnetoresistive layer, said conducting
layer comprising at least one equipotential strip which
extends at an angle to the longitudinal axis,
characterized in that located opposite each end
portion, on a side of the magnetoresistive element
remote from the conducting layer is a facing layer of
hard-magnetic material having an axis of magnetization
extending parallel to the longitudinal axis of the
magnetoresistive layer, and in that a non-magnetic
spacer layer of electrically insulating material is
